- and is thus arranged, that it can be operatedv pulleys a to an arm p on the brake, axle,

Be it known that I, HARALD "Energien FREDERIK Rumi BLOCK, captain, a subject of the King of Denmark, residing at Copenhagen, in the Kingdom of Denmarkkhavev invented .new and useful Improvements in Vehicle-Brakes, of4 which the following is a specification.

The object of the lpresent invention relates to a brake for motor-cars and like conveyances to beV use d in cases of emergency by any one sitting in the tonneau (in motorcars with seats for two only, from the pas sengers seats) so that a passenger can stop the motor and operate the brakes, should the chauffeur for one reason vor other be unable to put on the brakes or neglect to do'so.

A form of execution of the invention is shown .in the accompanying drawing, in

which- Figure l shows askeleton-like view of `theA emergency brake-apparatus placed on a motor-car, seen from the side, Fig'. 2 shows same from above, and Fig. 3 shows the brake handle in anormal position.

a is the lever, by' means of which the chaueur operates the brakes placed on the aXle b of the hind-wheels or on the aXle lof the fore-wheels.

. -A common form for a brake-construction on motor-cars or like conveyances is e. g'. the following: The lever a is placed on an axle c, which carries -a short arm al, on which is secured a drawing-rod, a rope or the' like, referred to as e, which is again connected with a short arml f, aiiiXed t'o the axle g, that rhas bearings in the substructure of the mo-l tor-car. 4At the ends of the 'axle g, there are short arms 7L, z', to which there 'is secured a cable, drawing-rods j, 7c, or the like, that' are connected with the brakes.

The emergency brake-apparatus'of the 'present invention consists of a wire-'rope g,

that is aliXed to a handle Z in theonneau (or near the passengersseats) and` is.car ried from this with-a round-turn around the motors driving shaft m, oversuitable guide which arm corresponds to. the arm f. Or-

dinarily the handle'l-is seated in a fork :a

(see Fig. 3), inwhich latter there are placed two contactsprings or like- .contacts s, by

` means of which thecurrent to the motors igniter t is either closed or broken (according to the manner in which .the igniter is constructed) when the handle vl with the contact ringor any other suitable contactdevice is carried into the fork.

The principle ofthe invention is to prevent the current of ignition from passing through the ignition tubes on the motor by removing the handle -from the fork or 4bythe `breaking ott' of the electric contact by the pull following the removal of the handle.

When the emergency brake-apparatus` is to be employed, the handle Z is pulled out of the fork 1, whereby the current from the igniter is broken off; by continuing to pull the handle the ropel g is tightened around the driving-shaft m, and on account of the'- on the axle in the friction it is wound up direction of its rotation, sothat the portion of the rope fastened to the arm pis thereby made shorter, whereby the arm is pulled forward in the same mannen, as is the case with the arm f, when the chauffeur carries the brake lever a back. If desired, the principle may beemployed in the brake on the driving shaft instead'of in the wheel-brakes or together `with them. v

Thehandle Z and the fork for same must be-affiXed to such, a'place, that the passenger, I

' Theform ofeXecution shown in the :drawing is only shown as an example, as the characteristic feature of the invention 1s the arrangement of one or other sultable organ 'placed in the motors tonneau and athxed to such a place that it is conveniently manipuy -v lated by the passengers; in its position' of res't this organ must close (or break as they case may be) the current ofignition to the motor, -while when the organ is pulled away from its normal position-whereby the motor is stopped-'fit simultaneously `,applies the brakes bymteans of any suitable llntermediate link.'A a

Having now described my invention, what I claim as ,new and desire to secureby Letters Patent is: y l

1. InI a motor-car in combination, -a wheelbrake', means for operating same from the chauifeurs seat only, a releasable handle said handle, with a round 't ,urn wound v 1,'10 placed in the tonneau, awire aiixedto-the i .ft

around-the driving-shaft of the motor and thereupon connected with the Wheel-brake,

guide-pulleys for the said Wire and means for breaking of the ignition of the motor, said latter means to be manipulated from the passengers" seats.

.2. In a motor-carin combination, a Wheelv tact-springs being each in connection with its part of the motorls current of ignition, a Wire afHXed to the said'handle with a round turnwound around the drivingshaft of the motor and thereupon connected with the Wheel-brakefandgude pulleys foi' the saidl Wire. 1'

Intestimony whereof I have signed my name to this specication in the presence of two subscribing Witnesses.
